. 13e4 it knownthat I, France W. Yasmin, of Little-v ton, inthe countyof Halifax andState of North Caro.-

lina, have invented anew and useful 'Improvement in 'Anti-Friction Journals; and I do hereby declare the following to be a clear and exact description thereof', sufcientto enable others skilled in .the lutto which my invention appertains to-make-and use the same,

reference beingv had to the accompanying -drawing formingpart'of 'this specification, v'in which- Figure 2 is a front elevation of a half ofthe same Figure' 3'is a modified form of iig. i.

Nature of Invention.

My present invention relates to an improvement -on my patent of March 29, 1870, N 101,401, and

consists in. arranging, in a suitable circular casing', aserics of single wheels or rollers and a series of double wheels or rollers, in ,such a manner that the shaft, axle, orv journal is surrounded by the double wheels,

and the pressure or friction distributed over a large surface, so that all or nearly all is bverclome or equali'zed.

In the drawing- A A is the box or casing, made of any suitable Inaterial, and forming bearings af a' for the journals of eight (more or less) single wheels, a a, the peripheries of which bear against theaxles of four (more or less) double wheels, l b,su bstantially as shown, the several wheels being constructed iu the samemanner as in my former patent, -the.dierenee being this,I that the wheels are alran'ged in a circle and entirely surround the shaft, axle, or journal B, so that it is impossible -ior the said shaft, axle, or journal toslip jorjump out, orto become otherwise disengaged therefromedimc'ulty experienced in my other invention.-

The box or casing A is made preferably in two lperipheries of the wheels aforming bearings for the The case may cover all the wheels or mayleave the Figure 1 is a side elevation ci xnyjdevice, partly in section;

double wheels exposed.

In operation the same manherofdistributing the friction or slip over a large surface is observed, as in my former patent, the pressure of the shaftbeing bogue equally by double andsingle wheels, and thus releving the shaft, axle, or journal.

.Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement, within a hollow or iecessedcasing, A, of a sexies -of single wheels, a a, and a se- -ries'ot' double wheels, b b,`arrange(l and operating of May, 1870.y
